ooda-skill

ooda-skill is a skill for Claude Code, Codex from mataeil/OODA-loop. It costs 25 tokens per session (2,529 once invoked), scanned A, original, MIT.

A guided tool for creating and managing project-specific domain skills. It creates SKILL.md instruction files after asking the user a short set of questions.

In plain words
What is it for?
Creating a new domain skill, turning an existing domain skill on or off, and listing each domain's status.
Why use it?
It removes the need to write, enable, or disable these instruction files by hand, while checking required setup and safety conditions first.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ooda-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ooda-skill — Domain Skill Wizard

Manages domain skills: create new skills via guided interview, disable or enable domains, and list current domain status. Generates a complete, project- specific SKILL.md by combining user answers with a generator template.


Step 0: HALT Check (Always First)

Read agent/safety/HALT. If the file exists: [HALT] ooda-skill blocked. Remove agent/safety/HALT to continue. — stop.

If config.json is missing: config.json not found. Run /ooda-setup first. — stop.

Parse the subcommand from the user's invocation: create | disable | enable | list Unknown subcommand → print Usage block and exit.


Subcommand: list

Print a table of all domains from config.domains, sorted by status then name.

Domain              Status      Skill
──────────────────────────────────────────────────
service_health      active      /scan-health
ux_evolution        available   /scan-ux
business_strategy   available   /scan-market
competitors         disabled    /scan-competitors

Status values:

  • active — skill created and configured, evolve will invoke it
  • available — domain defined in config, skill not yet created
  • disabled — domain exists but status set to "disabled"

Footer: Total: {N} domains — {N} active, {N} available, {N} disabled If config.domains is empty: No domains configured. Run /ooda-setup first.


Subcommand: disable {domain-name}

  1. Look up config.domains.{domain-name}. Not found → print Domain not found: {name} and exit.
  2. Already disabled → print {name} is already disabled. and exit.
  3. Back up config.json to config.json.bak.
  4. Set config.domains.{domain-name}.status = "disabled".
  5. Write and re-parse config.json to confirm valid JSON.
  6. Print:
    {name} disabled.
    Re-enable with: /ooda-skill enable {name}
    

Subcommand: enable {domain-name}

  1. Look up config.domains.{domain-name}. Not found → print Domain not found: {name} and exit.
  2. Check if a skill file exists at skills/{name}/SKILL.md.
    • If yes → restore status to "active".
    • If no → restore status to "available".
  3. Back up config.json to config.json.bak.
  4. Write updated status. Re-parse to confirm valid JSON.
  5. Print:
    {name} enabled (status: {active|available}).
    
    If status is "available": Run /ooda-skill create {name} to generate the skill.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
